• Screening Strategies in Primary Care
• Treatment Options
Case
• JB, a 49 yo gentleman with HIV on combination
antiretroviral therapy, tobacco dependence,
presents for routine care. He is concerned that
he is sleeping more than normal and he was told
that his blood pressure was elevated. Recent
labs revealed a detectable HIV-1 viral load of 110
copies.
• He admits to drinking 1 pint of vodka daily.
How do you quantify his alcohol use?
What is a Standard Drink?
NIAAA, NIH Publication No. 10-3770. 2010
What is a Standard Drink?
Approximately 10.5 drinks daily!

The Spectrum of Alcohol Use
Saitz R. NEJM 2005
Classification of Alcohol Use
Alcohol Pattern
Characteristics
Low-Risk (Moderate) Drinking
Men < 65 years old:
•<4 on any day
•<14 per week
Men > 65 years old and all Women:
• <3 on any day
•<7 per week
•Lower thresholds or abstinence might be
appropriate based on prescribed
medication; health conditions; pregnancy)
At-Risk(Heavy) Drinking
Men < 65 years old:
•>4 on any day
•>14 per week
Men > 65 years old and Women:
• >3 on any day
•>7 per week
Classification of Alcohol Use

Alcohol and Risk of Incident HIV
• Alcohol consumers overall had a
significantly increased risk of
becoming HIV positive
• This held true for each
consumption-type specific
analysis:
▫ Any consumption
▫ Binge
▫ Alcohol prior to sex

Addressing Alcohol Use Disorders
• BUT. . . how effective are physicians in
speaking about alcohol?
McCormick KA et al. JGIM 2006
Screening for Alcohol Use Disorders
• Routine examination
• Before prescribing a medication that interacts
with alcohol
• Emergency Department
• Pregnant
• Likely to drink (smokers, young adults)
• Alcohol-induced health problem
• Chronic illness not responding to treatment
Screening for Alcohol Use Disorders
“The USPSTF recommends that clinicians screen adults aged 18 years or older
for alcohol misuse and provide persons engaged in risky or hazardous drinking
with behavioral counseling interventions to reduce alcohol misuse. (Grade B
recommendation.)”
Screening Tests
• AUDIT – 10 item
• AUDIT-C – 3 items to quantify consumption
• Single question screening
▫ “How many times in the past year have you had 5
(for men) or 4 (for women and all adults older
than 65 yo) or more drinks in a day?”
Moyer V. Annals Internal Medicine 2013
NIAAA-Screening Approach
• 1. Do you sometimes drink beer, wine, or other
alcoholic beverages?
• 2. How many times in the past year have you had 5
(for men) or 4 (for women, all over 65 years old) or
more drinks in a day?
• 3. Quantify:
▫ On average, how many days a week do you have an
alcoholic drink?
▫ On a typical drinking day, how many drinks do you
have?
• 4. Assess for Alcohol Use Disorders
Case continued
What do you want to do now for JB?
Case continued
• He drinks alone daily; used to drink at bars but
moved and worried about driving.
• He has tried to cut down in the past but has been
unsuccessful; attended AA meetings briefly after
leaving jail.
• Last blackout one year ago; no withdrawal but
drinks daily.
Case continued
So, now what. . . ?
Treatment Goals and Options
At-Risk Drinking
Alcohol Use
Disorders
Decrease drinking to
below NIAAA-levels
Abstinence
Brief Interventions
Multi-Modal
Approach
At-Risk Drinkers: Brief Interventions
• 10 – 15 minutes
• Components:
▫ Feedback about drinking
▫ Advice and goal setting
▫ Follow-up contact
• Motivational interviewing principles
▫ Empathic listening
▫ Patient autonomy
▫ Patient-identified reasons for change
Saitz R NEJM 2005
Implementing Brief Interventions
Elicit patient view about the problem
Express concern and provide clear
advice
Provide feedback and norms, link to
current problems
Express empathy, reinforce change as
possibility, and acknowledge patient’s
responsibility
Provide menu of options for
promoting change
Anticipate and discuss difficult
situations

Evidence for Brief Interventions
Jonas DE et al. Annals Internal Medicine 2012
Alcohol Use Disorders:
Multi-Pronged Approach
Pharmacotherapy
Counseling
Self-Help
Counseling
• 12-Step Facilitation
▫ Encourages acceptance of having chronic disease, loss of
control and encourages abstinence
▫ Alcoholics Anonymous
• Cognitive Behavioral Therapy
▫ Functional analysis: identify thoughts, feelings and
circumstances of the patient before and after drinking
▫ Skills training: unlearn bad habits and learn new skills for
coping with problems
• Motivational Enhancement Therapy
▫ “Stages of change”
ACP 2009
Pharmacotherapy: Withdrawal
• >20 drinks per day, symptomatic withdrawal is
likely with abstinence
• Characterize with standardized instruments
▫ Clinical Institute Withdrawal Assessment Scale for
Alcohol
• Benzodiazepines – decrease symptoms, risk of
seizures and delirium tremens
• Adjunctive therapy – β-blockers, α-agonists,
neuroleptics, etc.
Saitz R NEJM 2005; NIAAA guidelines; ACP 2009
Pharmacotherapy: Relapse Prevention
• Minimum of three months of treatment
• Four FDA-approved treatment options
• No guidelines regarding combining medications
or order in which treatments provided
Disulfiram
Property
Description
Mechanism
Blocks aldehyde dehydrogenase causing build-up
acetaldehyde with alcohol consumption
Effect
Unpleasant feeling with alcohol consumption (flushing,
headache, vomiting, dyspnea, confusion)
Dosing
Initial dose 250mg daily  500 mg
Side Effects
Idiosyncratic fulminant hepatitis, neuropathy,
psychosis and symptoms that resolve with stopping the
medication (headache, drowsiness, fatigue, rash,
pruritus, dermatitis, garlicky taste in mouth)
Cautions
Increased reaction in patients with CAD, receiving
treatment for HTN, or with esophageal varices; need to
understand effects of medication; avoid if rubber,
cobalt or nickel allergy; pregnancy
Administration
Goal is abstinence; supervised dosing most effective
Clinical Effectiveness
Limited efficacy in clinical practice
Saitz R NEJM 2005; Franck J Current Opinion Neurobio 2013
Acamprosate
Property
Description
Mechanism
NMDA modulator to promote glutamate and GABA
balance; decreases dopamine excitability
Effect
Decreasing craving
Dosing
666mg three times daily
Side Effects
Diarrhea
Cautions
Contraindicated in renal insufficiency (creatinine
clearance < 30 ml/min); half a dose in those with
creatinine clearance >30-50 ml/min
Clinical Effectiveness
Variable data (negative results COMBINE and
PREDICT); most effective with detoxification prior to
treatment initiation and goal of promoting and
maintaining abstinence
Saitz R NEJM 2005; Franck J Current Opinions in Neurobiol 2013;
Maisel NC Addiction 2013
Naltrexone
Property
Description
Mechanism
μ-opioid receptor antagonist
Effect
Decreases euphoria with alcohol
Decreases alcohol craving
Dosing
Oral: initial dose 12.5mg or 25mg daily  50mg daily
Injectable: 190-380mg
Side Effects
Nausea, headache, dizziness, nervousness, fatigue,
insomnia, vomiting, anxiety, somnolence, dry mouth,
dyspepsia, elevated LFTs, depression
Cautions
Contraindicated in patients with opioid dependence or
prescribed opioids; relatively contraindicated in
patients with hepatitis or cirrhosis
Suggested Monitoring Symptoms and periodic LFTs
Administration
Saitz R NEJM 2005
Appropriate for those not committed to abstinence and
does not require abstinence prior to initiation
Acamprosate vs. Naltrexone
• Need to treat 8 people with acamprosate to
achieve an additional case of abstinence
• Need to treat 9 people with naltrexone to
prevent an additional case of return to heavy
drinking
Maisel NC Addiction 2012
Limited Prescribing
• Veterans with alcohol use disorders, FY2010
▫ Excluded patients with opioid medications
• Only 2.75% were prescribed naltrexone!
• Patients most likely to be prescribed naltrexone
▫

▫
Substance abuse outpatient visit: AOR=4.9
Any non-substance abuse psychiatric visit: AOR=2.6
Any mental health hospitalization: AOR=1.93
Other: comorbid depression or anxiety disorder
Iheanacho T et al. DAD 2013
Mutual Help Groups:
Alcoholics Anonymous
• One membership requirement: desire to stop
drinking
• Supports use of medications but some members
disapprove
• Meeting types vary
• Data demonstrates that participation is
associated with decreased drinking and
abstinence especially as part of primary
outpatient treatment
Saitz R NEJM 2005; Magura JSAD 2012
Alcoholics Anonymous
• Prescribe a certain number of meetings a week
• Ask about patient’s sponsor
• Know how to access meeting schedules:
▫ www.alcoholics-anonymous.org
• Encourage patients to try a different meeting
type or place if initially unsuccessful
• Attend a meeting yourself!
Summary
• Alcohol has a major impact on health conditions
of our patients
• Screening for alcohol use disorders is an
important first step
• Treatment approaches should be tailored based
on alcohol consumption
Summary
• Despite effectiveness of treatments, there is
variable implementation
• Internists are well positioned to deliver these
treatments!
